I'm currently attempting to apply this plugin to a list in which accesses the Twitter API. My question is, if there is a PullRefresh.js, why do we need a plugin to do this? I understand that the Sencha developers are trying to watch the build size, so does this mean they are simply adding a place holder for an optional plugin?

I followed the Readme for the Sencha Touch 2 port of the pull to refresh plugin and am receiving this error. Wasn't sure if anyone could shed some light on what may be happening.

Code:

TypeError: 'undefined' is not a constructor (evaluating 'new Ext.Anim')Failed to load resource: The requested URL was not found on this server.Error: [Ext.Loader] Failed loading 'sdk/src/ux/kohactive/RefreshableList.js', please verify that the file exists
